Hole saw for use with an oscillating multi-tool

Abstract

The objects of the present invention are achieved in a hole saw for cooperation with an associated oscillating tool having an output shaft that sequentially moves clockwise and counterclockwise and the output shaft includes a 1st drive interface coupling to the driveshaft which includes a cylindrical body having an axis and 1st and 2nd axial extremities; a 2nd drive interface fixed to a 1st axial extremity of the cylindrical body. The 2nd drive interface is dimensioned and configured for coupling clockwise and counterclockwise rotational movement of the 1st drive interface to the 2nd drive interface whereby the cylindrical body sequentially rotates clockwise and counterclockwise. Each of a plurality of teeth extend from the 2nd axial extremity of the body. Each of the teeth have 1st and 2nd opposed sharpened edges.

What is claimed is: 
     
         1 . A hole saw for cooperation with an associated oscillating tool having an output shaft that sequentially moves clockwise and counterclockwise and the output shaft includes a 1st drive interface coupling to said driveshaft which comprises:
 a cylindrical body having an axis and 1st and 2nd axial extremities   a 2nd drive interface fixed to a 1st axial extremity of the cylindrical body, said 2nd drive interface being dimensioned and configured for coupling clockwise and counterclockwise rotational movement of said 1st drive interface to said 2nd drive interface whereby said cylindrical body sequentially rotates clockwise and counterclockwise; and   a plurality of teeth extending from said 2nd axial extremity of said body, each of said teeth having 1st and 2nd opposed sharpened edges, each pair of said 1st and 2nd opposed sharpened edges of each tooth defining a plane,   each cross section of said cylindrical body taken in a plane perpendicular to the axis defining a circle;   each intersection of each such plane and each such circle defining a chord of a defined circle.   
     
     
         2 . The hole saw as described in  claim 1  wherein each of said plurality of teeth are identical. 
     
     
         3 . The hole saw as described in  claim 1  wherein each tooth edge is cut at a 30° angle.
